Facebook has just snapped up Israeli mobile data optimisation startup Onavo. No financial details of the deal have been officially announced, but news publication Calcalist says the takeover will cost Facebook between $150 million and $200 million (£93.8 million and £125 million). Onavo's app is designed to help users cut unnecessary costs by making efficient use of mobile data. The company, which was founded three years ago, will keep its Tel-Aviv offices, in turn meaning that Facebook will also acquire its first Israeli base. According to Onavo, it will work with Facebook on the Internet.org alliance, which is aimed at helping the billions of unconnected people on the planet gain improved access to Internet services.

LG has teased a handful of pictures of its upcoming G Flex smartphone, ahead of a suspected November reveal. According to Engadget and Android Authority, anonymous sources have confirmed that the handset will launch "sometime next month." The two publications also say that the G Flex will feature a giant 6in display. LG's forthcoming device is also expected to pack a quad-core Snapdragon 800 processor and Android 4.3 Jelly Bean. There is fresh gossip indicating that the smartphone's concave display will be made from plastic substrates instead of glass, making it flexible, but these rumours are as yet unconfirmed.

This One wasn't a well-kept secret. Taiwanese manufacturer HTC has today confirmed the arrival of the HTC One max, a high-end phablet following in the footsteps of the iPhone 5S with a built-in fingerprint sensor. The handset has been rumoured for some time with HTC now hoping a full trio of different-size One smartphones (the HTC One mini was also added this year) will revive the company's fortunes amid increasingly bleak financial reports. The HTC One max is kitted out as expected, sporting a large 5.9in, 1080p Full HD display, Qualcomm's Snapdragon 600 quad-core processor (rather than the updated 800 model), 2GB RAM, 16GB or 32GB storage with a microSD slot enabling expansion, the same 4-Ultrapixel rear camera as its One siblings, a 2.1-megapixel front snapper, 4G connectivity, and a beefy 3,300mAh battery.

Now that the iPhone 5S and 5C have been released, we can all turn our attention to what Apple is cooking up for next year. One change that's likely on tap for the next-generation iPhone: a larger screen, according to Cantor Fitzgerald analyst Brian White. In a recent note to investors, White said he gleaned information about Apple's iPhone 6 during a recent visit to China and Taiwan and an unnamed tech supply chain vendor. He believes that Apple will release the scaled-up iPhone in the second or third quarter of 2014. If history is any indication, the next iteration of the iPhone will feature a redesign. The iPhone 4 and 4S looked similar with a few internal tweaks, just like the iPhone 5 and 5S. But the iPhone 5 got a size boost to 4in from 3.5in, so Apple is likely considering a bigger screen for the iPhone 6.
